Engine classification

For two-stroke engines engines and four-stroke engines
Two-stroke engines: Where every one rotation of the engine crankshaft, namely two vertical reciprocating movement of the piston stroke and complete a work cycle of the engine. wave110 cub motorcycle engine Four-stroke engines: Where the engine crankshaft rotation every two revolutions, the vertical reciprocating movement of the piston stroke and four cycle engine to complete a job. Duty cycle refers to the engine by the intake, compression, combustion and expansion work process (acting), consisting of the exhaust stroke. Engine complete a intake, compression, acting, exhaust process is called a work cycle, also known as a cycle.

Motorcycle clutch classification

Motorcycle clutch classification
1) wet multi-plate friction clutch clutch assembly immersed in the oil, CG 125cc two wheel motorcycle engine divided active, driven and separated into three parts. Engine power initiative by sprocket gear cover, cover with a slot surrounding Wuzheng embedded friction plate rubber cork friction material (active tablets), its outer edge bumps placed in an active cover trench along with the rotation of the active part of the clutch. Four steel driven piece by piece fixed inside the driven gear connected basin constitutes driven portion. Lord, driven piece staggered installation, fixed basin connected by internal splines and the transmission shaft, four on the clutch spring gland, pressed against the friction plate and driven piece, motorcycle engine the power to the transmission. The clutch is normally engaged type, when Squeeze the clutch cable so that the collar by hand in the left cover rotation, the collar of the adjusting screw to the right to promote the release rod and the gland, the spring pressure disappears, friction syndrome and driven piece separation.
(2) automatic centrifugal clutch This structure is used in Yamaha CY80, Suzuki FR50 and other mopeds, according to the level of the engine speed is controlled automatically separated from the clutch engagement. Clutch by the initiative, driven and separate engagement mechanism. Active in part by the clutch housing, thrust washer, clutch and other components. Driven in part by the friction plate, center sets and other components.motorcycle engine When the engine is running, as the speed increases, the centrifugal force generated by the ball along with the increases, the axial thrust to overcome the spring tension along the trench separating clutch housing inside outward movement, push the film tight stop oppression press the clutch plate friction clutch in the engaged state levy, the power output. When the engine speed is reduced to idle or turn off, the ball is reduced or no centrifugal force to separate the ball centrifugal force to overcome the spring tension along the trench so that the ball back in situ, clutch.
(3) Shoe automatic clutch this structure is used in a number of miniature motorcycles, the active part driven by the crankshaft mounts, three hoof block assembly seat, and with a pin attached to the holder, spring shoes Block pull to the center of the crankshaft, so to maintain a certain gap between the hoof block assembly of the clutch disc and the driven part of the shoe. When the rotation speed increases, centrifugal force is greater than the hoof block the spring tension, throw it out, when the centrifugal force to a certain value on engagement with the clutch plate friction force to drive the driven part rotates, power is transmitted.

Two-stroke motorcycle engine works

C90 motorcycle manufacturer  point movement of the piston from the bottom up dead stop, it will complete the intake and compression work process, are reciprocating The first stroke movement. Downward movement of the piston from top dead center TDC, it will complete combustion and expansion (for power) and exhaust work process, it belongs to the second piston reciprocating stroke. Taxi two wheel motorcycle  from the point when the piston is at top dead center stop movement of all closed ventilation and exhaust ports, the exhaust and ventilation process is terminated, the cylinder fresh combustible mixture will begin early in the compression. Vertical motorcycle engine While the piston moves upward, the piston below the crankcase capacity increases, so the crankcase pressure drop and form a vacuum degree, when the degree of vacuum in the crankcase to a certain extent, the reed valves automatically open, the carburetor fog of the combustible mixture is drawn into the crankcase. When the piston continues upward movement, when the top dead center to be close to issuing a spark from the spark plug, which has been compressed combustible mixture ignited. In this case the rapid expansion of burning gases, the combustion chamber temperature and pressure rise sharply, forcing the piston downward movement, i.e. as useful work by the piston rod, a crankshaft. When the piston from the TDC TDC downward movement, the crankcase pressure will increase with decreasing volume, the reed valve will gradually shut down automatically, this time into the crankcase of the combustible mixture starts to be pre-compressed . When the piston down to the exhaust port open, exhaust gases through the exhaust port to the exhaust pipe, silencer into the atmosphere. When the piston then continue down to the ventilation port is enabled, the crankcase is pre-compressed fresh combustible mixture will enter through the ventilation opening of the cylinder, and drive the exhaust gas inside the cylinder further discharge, this process is called scavenging process. This engine will complete a cycle of work.

Electric motorcycle motor speed control device

Taxi two wheel motorcycle motor speed control device is set to transform the shift and direction of the electric car , its role is to control the motor voltage or current, complete control of the motor drive torque and rotational direction.

Before electric cars on DC motor speed using the series resistance or change the motor field coil turns to achieve. Because there is a level of speed and will produce additional energy consumption or use of a motor complex structure, it has been rarely used today. Today electric and motorized tricycle wider application of thyristor chopper controlled by uniformly changing the motor terminal voltage, controlling the motor current to achieve variable speed motor .
